APPARATUS FOR DISCHARGING RETORTS.

SPECIFICATION forming part of Letters Patent No. l715,004, dated December 2, 1902.

y Application filed February 5, 1902. Serial No. 92,731. (No model.)

To tZZ whom, it may concern.-

Be it known that I, LON BERTRAND, engineer, a citizen of the French Republic, residing at 6 Rue Condorcet,Paris,France, have invented certain new and useful Improvements in Apparatus for Discharging Retorts, of which the following is a specification.

This invention has for its object an apparatns intended to rapidly draw off the coke from gas-retorts, and it is so arranged that it may be confined in a very small space when not in use, while being capable of extending throughout (from one end to the other) long horizontal retorts. Apparatus according to this invention comprises a piston attached to a rack-beam composed of several sections of which each pair of adjacent ones is provided with an automatic locking device, so that the coke can be drawn out by a continuous action of the piston, each succeeding section being moved by the next preceding one by means of its locking device; and in order that my invention may be fully understood I will describe the same with reference to the accompanying drawings, of which- Figure 1 is a side elevation of the apparatus, the latter being mounted on a truck adapted to run upon rails on the chargingstage of the furnace. Fig'. 2 is a cross-section of the same. Fig. 3 is, on an enlarged scale, a longitudinal section of the rack-beam or telescopical beam, taken on the line A B of Fig. 4. Fig. 4 is a horizontal section through line CD of Fig. 3. Figs. 5 and 6 are crosssections of the same, taken on the lines E F and G I-I of Fig. 3, respectively.

The construction of the apparatus is asfollows: The piston l for discharging the coke is carried by a beam composed of three sections, which are mounted telescopically one within the other and are moved in succession.

Referring first to Figs. 3, 4, 5, and 6, the inmost section is an iron bar 2, which is placed on its edge and is furnished at its lower portion with a rack 2'. The two other sections of the beam are, as seen from Figs. 5 and in form of two large inverted channelbeams 3 4, provided along their lower edges with two racks 3 3 and 4 4', respectively. The outer section 4 is provided with four wheels 5, adapted to run between two pairs of upper and lower rails 6 G', screwed to uplper and lower bed-plates 7 7', forming a part of the frame of the machine. Said machine is suspended within four posts 8, Figs. 1 and 2, rising vertically from the platform of a truck 9, adapted to run on rails 10 before the charging side of the retorts. A suitable wrench and wire arrangement (of any known device) enables the frame to be raised and lowered, according to the height of the retort to be emptied, and rollers 11 serve to guide said frame between the posts S during the vertical displacements.

The inmost portion 2 of the rack-beam bears with its forward end on a toothed wheel 12, keyed on a shaft 13, which turns in bearings secured to the lower bed-plate 7 of the frame. The said inmost portion 2 is provided at its rear end with two lugs 14, tted with rollers 15, bearing on the horizontal parts of the beam 3. In a similar manner the part 3 of the beam is provided at both ends with lugs 16 16, fitted with rollers 17 17', which run on the horizontal flanges of the outer sections 4 of the beam. The pair of racks 3 of said portion 3 are adapted to engage with toothed wheels 18 18, Fig. 5, keyed also on the shaft 13; but they are not engaged with these wheels when the beam is in its normal position. The pair of racks 4' 4 of the outer portion of the beam are adapted to engage with two toothed wheels 19 19 on the shaft 13 when the beam is pushed forward to a sufiicient eX- tent.

The portions 2 and 3 and 3 and 4, respectively, may be ,locked together by means of the following locking device:

In the two vertical walls of the section or channel 3 are secured screw-threaded pins 19, on which run pinions 20, integral with pins 2l. Said pinions engage with pinions 22, keyed on a shaft in bearings mounted on the horizontal upper ange of the channel 3, said pinions 22 being adapted to come into gear with racks 23, secured under the upper bed-plate 7 of the frame of the machine.

v The inner part 2 of the beam is fitted near its rear end with a hole 24, the position of whichis such that when the Said part 2 has been pushed forward and its rollers 15 are stopped by the abutments 25 on the channel 3, Figs. 4 and 3, the said hole is justopposite to the two pins 21. It is understood that ICG when in this position if the pinions 20 are turned (rotated) on the screws 19 the pins will engage in the hole 24, and the portions 3 and 2 of the beam are keyed together. A similar locking device is provided for the portions 3 and 4, as shown in Figs. 4 and 6.

On the vertical walls of the section or channel 4 are secured screws 26, on which run pinions 27, integral with pins 28, said pinions engaging with pinions 29 on a shaft 30, secured to the upper ange of the channel 4. These pinions are adapted to come into gear with racks 31, arranged parallel to the aforesaid racks 23.

The two flanges of the portion 3 are provided with holes 32 32 near their rear end in such a position that when the rollers 17 at the rear of the-channel 3 strike against the stationary abutments 33 of the channel 4 the holes 32 are just opposite the pins 28, which can engage therewith if the pinions 27 are rotated on the screws 26.

The successive movements of the telescopic beams 2 3 4 are effected in the following manner: On the upper bed-plate 7 of the machineframe is an electric motor 34, Figs. 1 and 2, which drives, by means of a shaft 35, a reversible clutch 36, and bevel-Wheel gear 37 37 the shaft 13, which carries the series of wheels 12, 18 18, 19 and 19. The rack 2 of theinner portion 2 of the beam being always in engagement with the gear-wheel 12, as soon as the motor is set in motion the said section 2 is pushed forward. When the rollers 15 15 at the rear end of said portion 2 strike against the abutments 25 on the channel 3, this latter is also carried forward. During this displacement the pinions 22 22 on the channel 3 roll on (or under) the stationary racks 23 23, Figs. 3 and 5, and cause the pinions 20 to run on the screw-threads 19, and as the pins 21 are opposite to the holes 24 in the portion 2, as aforesaid, they engage therewith, and the portions 2 and 3 of the beam are locked together. The channel 3 having been displaced to a slight extent, its racks 3' are brought into gear with the toothed wheels 18 18, and as the latter are in movement the section 3 (together with the portion 2, the rack of which has left the wheel12) is pushed forward. When the rollers 17 17 of the channel 3 strike the stationary abutmenvts 33 of the channel 4,v the latter is withdrawn and the pinions 29 29 roll under the stationary racks 31 31, Fig. 6,l and these cause the pinions 27 to run on the threads 26 and their pins to engage the holes 32 32 in the channel 3. The portions 3 and 4 are thus locked together in the same manner as the portions 3 and 2. During this movement of the channel 4 its racks 4 4 have been brought in engagement with the wheels 19 19, and as the latter are also rolated from the shaft 12 the channel4 is pushed forward,together with the two sections 3 and 2, locked thereto. As stated above, the channel 4 is supported by wheels 5 running between two rails 6 6.

It will be understood that if 'oy means of the clutch 36 the rotation of the gear 37 is reversed, the several portions of the beam are retracted and that they become unlocked from each other in the same manner they were locked during their forward movement.
